Difference Between UNI Flange Series 1400 And Series 1300

Unlike traditional threaded and welded flanges, the UNI Flange range 1400 allows for pipe bending during assembly. It implies the uni flange torque can achieve a contact when other methods fail.
The pipe wall is fully circumferentially supported and is in contact with by the Series 1300. This is advised by many pipe makers and is crucial when using pipes with thinner walls.

UNI Flange Installation Instructions

By moving the flange ring into place with the seal in place, line up all of the fastener holes on the matching flanges. All screws, nuts, and flat washers should be inserted. Before fastening the flanges, make sure the sides of the mating surfaces are level with the gasket.
Move the flange forward when the gasket is uniformly placed in the flange chamber. The Uni-Flange face is level with the tube's end. Match the Uni-Flange to the regular flange with normal flange bolts. Before exerting torque, equally move all set nuts to the pipe wall. Unlike other systems, the Uni-Flange has the advantage of allowing pipe deflection during assembly.
Keep in mind that extra measures may be required for surges.

What Is A UNI Standard Flanges

UNI Standard Flanges avoid the issues associated with pre-engineered, premade pipe networks. On-site pipe fabrication is possible with plain end piping system, a pipe cutter, and a spanner. There is no need for threading, welding, and grooving.

Purpose Of Italian Standard Flange

The pipe restraints offer a quick and affordable way to secure water main fittings, faucets, and hydrants. These restraints, which are offered for PVC and Ductile pipe, ensure consistent joint restraint in all soil conditions.A flange standard sets down the size, better surface, facing type, material and technical standards for flanges.
The significance of Italian Standard Flange is seen while connecting piping elements together. Modern forging, cutting, polishing, inspection, and packaging machines and equipment use materials like carbon steel and special alloys to manufacture flanges.

Questions & Answers

Questions : Can Uni-Flanges be used face to face?
Answers : Yes, a metal ring or spacer must be placed between the flanges. These are available from the factory.
Questions : Can Uni-Flanges be used on steam or gas?
Answers : It is not recommended for prolonged use on steam due to temperature. However, it is excellent for gas when supplied with a NBR (Buna-N) gasket.
Questions : Uni-Flanges be used on temperature applications?
Answers : Yes. Our various gaskets will handle most temperature ranges. Refer to technical data for gasket availability.
